The EZ-ZONE
®
PM takes the pain out of solving
your thermal loop requirements.
Watlow’s EZ-ZONE
®
PM controllers offer options
to reduce system complexity and the cost of control-
loop ownership. You can order the EZ-ZONE
®
PM as
a PID controller or an over-under limit controller, or
you can combine both functions in the PM Integrat-
ed Limit Controller. You now have the option to in-
tegrate a high-amperage power controller output, an
over-under limit controller and a high-performance
PID controller all in space-saving, panel-mount
packages. You can also select from a number of se-
rial communications options to help you manage sys-
tem performance.
It just got a whole lot easier to solve the ther-
mal requirements of your system. Because the EZ-
ZONE
®
PM controllers are highly scalable, you only
pay for what you need. So if you are looking for a
PID controller, an over-under limit controller or an
integrated controller, the EZ-ZONE
®
PM is the an-
swer.
